Why do we need encryption in PostgreSQL database?
Encryption Options. PostgreSQL offers encryption at several levels, and provides flexibility in protecting data from disclosure due to database server theft, unscrupulous administrators, and insecure networks. Encryption might also be required to secure sensitive data such as medical records or financial transactions.
How is the pgcrypto module used in PostgreSQL?
The pgcrypto module allows certain fields to be stored encrypted. This is useful if only some of the data is sensitive. The client supplies the decryption key and the data is decrypted on the server and then sent to the client.
How are passwords stored in a PostgreSQL database?
Database user passwords are stored as hashes (determined by the setting password_encryption ), so the administrator cannot determine the actual password assigned to the user.
How to secure the source code of PostgreSQL?
The system should only be configured to listen for and accept connections on the networks that are actually required; by default, a source code build of Postgres will listen only on the localhost or loopback address, which prevents connections from other machines.
Is there Transparent Data Encryption in pgSQL hackers?
This page describes the transparent data encryption feature proposed in pgsql-hackers. There has been continual discussion about whether and how to implement Transparent Data Encryption (TDE) in Postgres. Many other relational databases support TDE, and some security standards require it.
Where is the master key stored in PostgreSQL?
The master key can be obtained from external systems via a key ring plugin [14] MySQL encrypts each page of both redo log and undo log with dedicated keys, not with the keys used for table encryption. The encryption key is stored in the header of the first redo/undo log file in encrypted state.
